Hello, my question is will this be acceptable.
Here I have 2 rooms beside each other but need a toilet in both on the ground floor before 150mm insulation and 75mm screed get installed. One room is a bathroom, the other an ensuite. The toilet in the left will have a 90 bend under it and will be going into a 110mm pipe with a fall of 1/40 or slightly less. It will have a tee on it just before it leaves the exterior wall and will connected to another toilet above. Both pipes will be 150mm of the wall from the furthest part of the pipe. Once the pipe leaves the house it will have 2 x 90s which will be connected to an inspection chamber which will be connected to a septic tank with a 1/40 fall in the pipe.
In the toilet on the left it will have an air admittance valve to stop any back suction from the other toilet.
The bathroom with the exterior wall will be 2.4m wide. Enough to get the 1/40 fall needed for the waste water to get away without any issues.
Originally there was only supposed to be one toilet but now another needs added in the small box room on the left.
I could have an option of a saniflow toilet in left room but what I describe above would be my preferred option.
Another question I have about the rain water drainage. I have a run of 22m and the underground pipe will be 10inch black corri pipe. What would be the minimum fall I can get away with if the underground with this pipe. Can I go shallower that 1/110.
First fix going in in the next few days and all swift replies will be much appreciated. TY.
